Question
### Educational Content: Understanding Catalysts in Chemical Reactions **Question 15: How does a catalyst increase the rate of a chemical reaction?** - ○ A catalyst lowers the energy of the products. - ○ A catalyst increases the probability of a reactive collision. - ○ A catalyst increases the energy of the reactants. - ○ ***A catalyst lowers the activation energy of the reaction.*** #### Explanation: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. The correct choice is: "A catalyst lowers the activation energy of the reaction." By lowering the activation energy, a catalyst provides an alternative pathway for the reaction to occur, making it easier for reactant molecules to transform into product molecules. This process significantly speeds up the reaction without altering the final energy states of the reactants or products.
